Oh, I see what's going on.
In, for example, RHEL-8 xlog_get_iclog_buffer_size() on entry we
have:
if (mp->m_logbufs <= 0)
log->l_iclog_bufs = XLOG_MAX_ICLOGS;
else
log->l_iclog_bufs = mp->m_logbufs;
which sets a struct xlog field but leaves the struct xfs_mount
alone.
But upstream on entry we have:
if (mp->m_logbufs <= 0)
mp->m_logbufs = XLOG_MAX_ICLOGS;
if (mp->m_logbsize <= 0)
mp->m_logbsize = XLOG_BIG_RECORD_BSIZE;
which sets the struct xfs_mount fields before continuing.
There's a lot more going on in xlog_get_iclog_buffer_size() so this
is a very simple minded comparison on my part but the point is
RHEL-8 (and I'm assuming RHEL-7 too) is different to the current
xfs upstream.

So I'd still like more info around this difference please Dave.
